Unusual ultrastructural findings in dendrites of pyramidal neurons in the cerebral cortex of rabies-infected mice
Previous studies using the Golgi technique have demonstrated alterations in the dendritic morphology of pyramidal neurons of the cerebral cortex of mice inoculated with the rabies virus. However, knowledge about the fine structure of dendrites in rabies infection is scarce. This work had the aim of studying the ultrastructure of dendrites in cortical pyramidal neurons of rabies-infected mice. M...
متن کاملSchwannoma with features mimicking neuroblastoma: report of two cases with immunohistochemical and ultrastructural findings.
OBJECTIVE A study of two cases of a rare variant of benign schwannoma showing areas mimicking neuroblastoma/peripheral primitive neuroectodermal tumour (PNET). METHODS Sections of formalin fixed, paraffin embedded specimens were studied by tinctorial stains and immunohistochemistry, and the tissue retrieved from formalin was examined by electronmicroscopy in one case. RESULTS The tumours we...
متن کاملUnusual neurological presentation of neuroblastoma.
Acute cerebellar ataxia and opsomyoclonus are presenting signs of occult neuroblastoma for a substantial proportion of paediatric patients. Cerebellar ataxia may be due to antibodies against the neuroblastoma cross-reacting with cerebellar tissue. This report is of a 26-month-old boy who presented with encephalitis-like features of ataxia, seizures, decreased consciousness, and involuntary move...
متن کاملScrolls of Descemet's membrane as unusual giant nodules on the posterior cornea: histochemical and ultrastructural findings.
Unusual giant nodules on the posterior surface of Descemet's membrane were observed in two out of over 400 corneae examined during routine histopathological reporting. Both of the patients, a 60-year-old man and a 26-year-old woman, had histories of corneal trauma. Neither was associated with chronic keratitis or corneal dystrophy. Light microscopy showed these nodules to be composed of materia...
متن کاملUltrastructural findings in feline corneal sequestra.
OBJECTIVES (1) To describe the ultrastructural features of corneal sequestra in cats; and (2) to enhance our understanding regarding the pathogenesis of feline corneal sequestration. METHODS Nine corneal sequestra were harvested via keratectomy from globes of nine cats. The sequestra were routinely fixed then postfixed for high resolution light and transmission electron microscopy (HR-LM and ...
